MOTOR SUPPORT FOR WASHING- MACHINES.

Applcation filed October 15, 1923. Serial No. 668,594.

To all 107mm t fnmfz/ concern.'

Be it known that I, CARL A. OLSON, a cit-izen of the United States of America, and resident of Clarinda, Page County, Iowa, have invented a new and useful Motor Support for Washing Machines, of which the following is a specification.

The object of this invention is to provide new and improved means for mounting and supporting an electric mo-tor on and relative to a washing machine and relative to speedreducing gearing employed in the operation thereof.

A further object of this invention is to provide an improved motor support including means for directly connecting a motor casing to a gear housing and auxiliary means carried by a machine element for relieving strain on the main support.

My invention consists in the construction, arrangement and combination of `elements hereinafter set forth, pointed out in my claims and illustrated by the accompanying drawing, in which- Figure 1 is an elevation showing a portion of a washing machine and driving mechanism therefor, together with an electric motor and my improved support therefor in position for practical use, some of the elements being shown in section. Figure 2 is an elevation, partly in section, at right angles to Figure 1..

ln the construction and mounting of the device as shown the numeral designates the tub of a washing machine having a cover member 11 on which is mounted a casting 12 forming al portion ofthe support for the driving mechanism and also a gear housing 13. In this instance a train 14 of spur gearing is shown in the housing 13, through which power is transmitted to the driving mechanism at reduced speed from an electric motor 15, on the shaft 16 of which is a bakelite pinion 17 located within the housing 13 and meshing with the first member of the train 14.-. The motor is located at one side of and near the top of the tub 10 and the shaft 16 thereof is arranged in a hori- Zontal plane and extends toward a portion of the gear housing 13 which projects laterally from the tub.

A substantially L-shaped cradle is provided for the motor and includes a horizontal arm 18 extending beneath and Substantially in the plane of the axis of the motor, and a vertical arm 19 integral with and extending upwardly from said horizontal arm and crossing the axis of the motor shaft. linge 20, 21 preferably are formed on and extend oppositely from the horizontal arm 1S of the cradle, said wings engaging the lower surface of the motor, in certain instances being curved to conform to the curvature of the motor, as here shown, or they may be otherwise shaped to fit the motor case, to which they may be attached by means of screws 22. The vertical arm 19 of the motor cradle is formed at its upper end with a circular head 23 formed with a central circular hole 24 of suiiicient` diameter to permit the free passage of the motor shaft 16. The head 23 is formed on its face adjacent the motor with a counterbore 25 or recess concentric with its bore 24, adapted to receive snugly a circular boss 26 formed on the end of the motor case concentric with the shaft 16. On its opposite face thehead 23 is formed with a circular boss or projection 27 adapted to fit snugly with a circular hole 28 in the adjacent wall of the gear housing 13. The head 23 is formed with diametrically opposed tapped holes 29, 30 adapted to be brought into alinement with registering holes formed in the opposed walls of the gear housing 13, which is flat and relatively narrow as shown in Figure 1. Cap screws 31, 32 are adapted to be mounted through the holes in the walls of the housing 13 and seated in the tapped holes 29, 30 of the head 23 of the motor cradle, said cap screws being spaced sufficiently to clear the pinion 17.

The pinion 17 is mounted on the shaft 16 after the motor is mounted on its cradle,

and then the assembly is attached to the machine by inserting the boss 27 of the head 23 in the opening 2S of the housing and inserting the cap screws 31, This connecting means is sufficient to support the normal weight of the motor and also insures proper alinement and centering of the shaft and pinion relative to the gears in the housing.

It is desirable, however, to provide an auxiliary support for the motor toguard against undue strains such as the placing of additional weight thereon and against impact of foreign objects. An L-shaped bracket 33 is mounted a ainst the side of the tub 10 and held in p ace by bolts, screws or other securing means, 34 The horizontal arm of the bracket 33 extends beneath and across the horizontal arm 18 of the motor cradle, and an adjusting screw 85 is threaded in said bracket arm, from below, and adapted to engage at itslend the lower surface or' said arm 18, to furnish additional and adjustable supporting means for the cradle and motor, at a point spaced inaterially from the suspending connection to the gear housing. The adjusting screwB may be provided with a lock nut 3b'. A wedge'- shaped member is mounted against the vertical arm of the bracket 33 and is formed with a longitudinal slot B8 through which passes a bolt 39 engaging'said arm, whereby` the member is adjustabl)7 supported lon the bracket. rlhe wedgeeshap'ed member 37 has an inclined outer face adapted to engage beneath the curved side of the motor case and assist in supporting the same.

l claim as 'my invention'- 1. The combination with a motor and a driving mechanism having a housing, of a supporting means for said 'motor eomprising a cradle having one arm extending beneath said motor and the other arm formed with a fiat head vprojeci-,ing between the motor and housing and provided with an opening for the passage of the motor shaft, said 'head being formed on one `tace with a boss received snugly iin a'n aperture in said housing andon its opposite Aface with a coun- 'terbo're receiving snugly a boss on 'said motor, and cap screws extending through said housing and seatedw'in said head.

2. The combination with a motor and a driving mechanism having a housing7 of a supporting means for said motor comprising a cradle having one arm extending beneath said motor andthe `o'the'r arm formed with a flat head projecting between the motor and housing and provided with an opening -Ltor `the passage of the motor shaft, said head 'being formed en 'opposite faces with slip-joint connections between said motor and housing respectively, securing means between said housing and head, and

an auxiliary support comprising a bracket extending beneath said motor ant having an adjusting' screw adapted for engagement therewith.

rfhe combination with a motor and a driving mechanism having a housing, of a supporting means v'for said motor comprising a cradle having one arm extending beneath said motor Aand the other arm formed with a Hat head projecting between the motor and housing and provided with an opening lier the passage of the motor shaft, said head being 'formed 'on opposite 'faces with slip-joint connections between said Vmotorand housing respectively, seciiring means between said housing and head, and an auxiliary support including a fixed bracket and a wedge shaped member radjustably rmounted on said bracket and adaptedl vforengagement with said motor.

4. The combination with a motor and 'a Vdriving mechanism having 4a housing, of
